321.473 Limiting trucks--rubbish vehicles.

Local authorities with respect to highways under their jurisdiction may
also, by ordinance or resolution, prohibit the operation of trucks or other
commercial vehicles, or may impose limitations as to the weight thereof, on
designated highways, which prohibitions and limitations shall be designated by
appropriate signs placed on such highways.

The department may issue annual special permits for the operation of compacted
rubbish vehicles and vehicles which transport compacted rubbish from a rubbish
collection point to a landfill area, exceeding the weight limitation of section
321.463, but not exceeding a rear axle gross weight for two-axle vehicles
of twenty-two thousand pounds for the period commencing July 1, 1978 and
ending June 30, 1986 and twenty thousand pounds commencing July 1, 1986
and thereafter, and for tandem axle vehicles or transferable auxiliary axle
vehicles not exceeding a gross weight on the rear axles of thirty-six thousand
pounds. Annual special permits for the operation on secondary roads shall
be approved by the county engineer. Annual special permits for a particular
vehicle shall not be issued by the department unless prior approval is given
by the county engineer of the county in which the vehicle will be operated.
Annual special permits for operation on primary roads shall be approved
by the state department of transportation. Compacted rubbish vehicles and
vehicles which transport compacted rubbish from a rubbish collection point
to a landfill area operated pursuant to an annual special permit shall be
operated only over routes designated by the local authority. Annual special
permits for a particular vehicle shall not be issued by the department unless
approved by the local authority responsible for the roads over which the
vehicle will be operated. Annual special permits approved by the issuing
authority shall be issued upon payment of an annual fee, in addition to
other registration fees imposed, of one hundred dollars to be paid to the
department for all nongovernmental vehicles.

Any person who violates the provisions of the ordinance or
resolution shall, upon conviction or a plea of guilty, be
subject to a fine determined by dividing the difference
between the actual weight and the maximum weight established
by the ordinance or resolution by one hundred, and multiplying
the quotient by two dollars. The fine for violation of a
special permit issued pursuant to this section shall be based
upon the difference between the actual weight of the vehicle
and load and the maximum weight allowed by the permit in
accordance with section 321.463.

Local authorities may issue special permits, during periods such restrictions
are in effect, to permit limited operation of vehicles upon specified routes
with loads in excess of any restrictions imposed under this section, but
not in excess of load restrictions imposed by any other provision of this
chapter, and such authorities shall issue such permits upon a showing that
there is a need to move to market farm produce or to move to any farm, feeds
or fuel for home heating purposes.
